Description

[0001] The present disclosure pertains to the technical field of sports equipment; specifically, it relates to a foldable treadmill. BACKGROUND

[0002] With the continuous improvement of people’s living standards, physical exercise has attracted increasing attention, and more and more people have purchased treadmills and placed them in their homes for regular exercise. Since it needs a certain display space and is not suitable for households with small indoor areas, a treadmill is designed to have a running board in a foldable structure, and has the running board folded when not in use, thereby reducing the space occupation.

[0003] In the prior art, folding is realized by mounting a hinge structure between a front running board and a rear running board. Due to the space required for hinges mounted between the front running board and the rear running board, there is a certain gap therebetween. During movement, if one steps into the gap, a front end of the front running board or a rear end of the rear running board will tilt upwards, affecting the overall stability of the treadmill. SUMMARY

[0004] To solve the above-mentioned problem in the prior art, the present disclosure provides a foldable treadmill with high stability.

[0005] To achieve the above objective, the present disclosure adopts the following technical solution: a foldable treadmill comprises a first running board and a second running board connected thereto through hinges; the first running board has a bottom portion that is supported by and connected to a first support frame, which is connected to a first roller; the second running board has a bottom portion that is supported by and connected to a second support frame, which is connected to a second roller, a belt is wrapped around the first roller and the second roller, and driven as the first roller and the second roller rotate; the first support frame comprises a first support member and a second support member, which are vertically connected to each other through a bolt; the second support frame comprises a third support member and a fourth support member, which are vertically connected to each other through a bolt; the first frame and the second support frame are detachably connected to each other through a bolt, which facilitates mounting the belt.

[0006] The third support member has a front end, which corresponds to a rear end of the first support member; the front end of the third support member is fixedly connected to a first fixing member, and a front end of the first support member is fixedly connected to a second fixing member; in an unfolded state, the first fixing member and the second fixing member are engaged against each other; as a support structure is added for the gap between the first running board and the second running board, the problem of tilting upwards will not occur even if a sporter steps on the real- end of the first running board, because upon the arrangement of the first fixing member and the second fixing member, a first connecting rod and a second connecting rod play the supporting role, so that the first running board and the second running board stay in a stable state.

[0007] A silent silicone pad is arranged on a relative surface of the first running board and the second running board.

[0008] The first running board is fixedly connected to a first connecting seat, and the second running board is fixedly connected to a second connecting seat; the first roller is connected to the first connecting seat through a bolt, and an elastic component is arranged on the bolt; the second roller is connected to the second connecting seat through a bolt, and an elastic component is arranged on the bolt.

[0009] The first running board and the second running board are fixedly connected to an anti-slip film, which is arranged below the belt; a free zone is arranged on the anti-slip film, and corresponds to a joint between the first running board and the second running board. The arrangement of the free zone on the anti-slip film, i.e., the arrangement of folding allowance, smoothens the process of folding or unfolding the first running board and the second running board, ends up without wrinkles, and improves the product quality.

[0010] According to the present disclosure, it further comprises a third support frame, which is fixedly connected to the front end of the first support frame and used for mounting a motor.

[0011] According to the present disclosure, further, the anti-slip film is fixedly connected to upper surfaces of the first running board and the second running board by means of bonding.

[0012] According to the present disclosure, further, an elastic component is arranged on the bolt of the first connecting seat, and the elastic component has one end in a drawing direction, which end is connected to a connecting head of the first roller, and the other end that is fixedly connected to the first connecting seat. The position of the first roller is limited, so as to solve the problem that the belt is deviated by changes in the position of the first roller, forward or backward, relative to the first running board in the unfolding process.

[0013] According to the present disclosure, further, an elastic component is arranged on the bolt of the second connecting seat, and the elastic component has one end in a drawing direction, which end is connected to a connecting head of the second roller, and the other end that is fixedly connected to the second connecting seat. The position of the second roller is limited to solve the problem that the belt is deviated by changes in the position of the second roller relative to the second running board in the unfolding process, forward or backward.

[0014] According to the present disclosure, further, the silent silicone pad adopts a shape of small rectangular blocks, separately arranged at both ends and middle of a rear surface of the first running board, and / or at both ends and middle of a front surface of the second running board.

[0015] The foldable treadmill of the present disclosure has the following beneficial effects. As the support structure is added for the gap between the first running board and the second running board, the problem of tilting upwards will not occur even if a spotter steps on the rear end of the first running board, because upon the arrangement of the first fixing member and the second fixing member, the first connecting rod and the second connecting rod play the supporting role, so that the first running board and the second running board stay in a stable state.

[0016] The arrangement of the free zone on the anti-slip film, i.e., the arrangement of folding allowance, smoothens the process of folding or unfolding the first running board and the second running board, ends up without wrinkles, ensures that the middle positions of the first running board and the second running board are flat, provides good experience results, and improves the product quality.

[0017] The position of the second roller is limited to solve the problem that the belt is deviated by changes in the position of the second roller, forward or backward, relative to the second running board in the unfolding process.

[0018] The silent pad is arranged to avoid noise or abnormal sound between the first running board and the second running board during use.

[0019] The arrangement of the first fixing member and the second fixing member, i.e., a butt screw, can keep the second running board and the first running board flat, so that the phenomenon that the first running board tilts upwards will not appear.

[0020] By adding the elastic components to the first roller and the second roller, the belt can be automatically reset, instead of deviation. BRIEF DESCRIPTION OF DRAWINGS
